A pressure-induced torque is emphasized in externally pressurized bearings having deep pockets, due to the pressure buildup by shaft rotation on the downstream vertical side of the recess. A standard simplified analysis is presented for both laminar

The way in which scientific research in Romania was funded before 1989, exclusively through the Council for Science and Technology, is briefly described. After 1989, this Council was abolished and many of its functions were given first to the Ministr

We are devoted to the study of a supersonic lifting line theory intended to provide both a means of aerodynamic calculation and a benchmark for the validation of the control point position for the related constant pressure panel methods. The model is

The existing narrow-groove theory is used for evaluating leakage flow for various configurations which might be of interest in seal design, including variable angle, film thickness and groove/ridge length ratio.

A previous analysis of dynamic stability for a blocked center inward pumping spiral grooved thrust gas bearing is extended to two other types of similar bearings, namely annular thrust bearings with either inward or outward pumping. Both a numerical

As mentioned in Chapter 2, the thermal problem is decoupled from the flow problem if the fluid is incompressible and has constant properties, particularly viscosity. Therefore, thermal problems under those circumstances concentrate on solving the ene

The study of the flow of a compressible fluid is obviously more difficult than that of an incompressible fluid. The number of unknowns is increased, fluid properties are dependent on other variables, and the temperature field can no longer be decoupl

Fluid mechanics aims to provide qualitative descriptions of flow and equilibrium of fluids under various circumstances encountered in applications. The scale of such studies is almost always much larger than the scale characterizing the physical stru

As already mentioned in the previous chapters, the problem of determining the motion of a viscous fluid in the general case and for larger Reynolds numbers is almost impossible to solve analytically, due first to the coupling of nonlinear inertia eff

Many of the problems already presented dealt with situations where inertia forces were cither zero (parallel flow) or could be neglected because of some peculiarities, for example, flow in thin layers. A larger class of flows with negligible convecti
